Y 9` claims. (c1. 164-93) Our invention relates to an adjustable Work supportof the anvil type, particularly for shoe tip presses and cut-out machines with which shoe uppers are ornamented, perforated or out out in 5 which the uppers are draped over the work sup` 'port with parts of the upper disaligned from the plane of the supporting surface of the support. This application is a divisional of application Serial No. 80,903, led January 13, 1926.

In machines for doing cut-out work and in machines for perforating and otherwise ornamenting shoe elements, the mechanical principle involved' usually consists in either moving a cutting or perforating die into engagement against a shoe element or in providing a moving punch block or plunger which carries the shoe element into engagement with a cutting die, in each case the object being to-cut out or ornament the shoe element with designs of the desired size and shape. The particular invention disclosed herein relates to a Work support for a cut-out machine such as is described and claimed inthe United States patent to Freeman No. 1,681,033, of August 14,

. In the parent case Serial No. 80,903, iiled Janu- -ary 13, 1926, we have particularly described and claimed an adjustable work support and although ythe broad principlev of providing an adjustable work support iscovered in this parent case, there are anumber of improvements suggested in one particular modification which was introduced in this case which were considered of such importance as to warrant an independent divisional application thereon in which the several improvements could be ,more speciiically disclosed and claimed. i

While in the Freeman Patent No. 1,681,033 a slidable work support which is movable from work `placing to operating position is shown which will 40 vpermit of the draping of a closed or fitted upper around the support, no provision was made for varying the elevation of the support to permit the use of diierent sized and shaped dies, anvils or masks without an adjustment of the stroke of the reciprocating' plunger or platen.

It is the object of our invention toprovide a die supporting unit'which will permit the movement of an ornamenting die from a workplacing to operating position and which will be provided with means for elevating the die to a desired ele- Vational position with referenceto the pressing head. Another object is the provision of a portion of the support with a'sharp edged angular ribbedupper'surface which will allow the die unit 1 ordinarily. consisting of a plate withvcuttingdiesA mounted thereon to seat in proper aligned position even though scraps or cuttings haveinad- 'vertently fallen on such upper surface. 4

Another object is the provision of a die support having a cooperating part which may be so conf I nected with a iixed part of the machine frame as to provide a stop and support for an overhanging end of the die. A still further object` is the provision of a guiding member for the die support which will permit the elevation of the die support 4'out which has itself no sliding movement from work placing to work operating position. Y The above and other objects to which reference will be made in the ensuing disclosure we accomplish by that certain combination and arrangement of parts of which we have shown a preferred embodiment.

In the embodiment of our invention illustrated in Figures 1 to 5, we have illustrated a preferred type of what is known to the trade as the anvil -type of bed, which provides sufhcient clearance at the sides, back or front or underneath so that assembled or partly assembled uppers maybe applied to the work support and the cut-out vor ornamenting workmay be done at a much -inore convenient and economical period in the construction` of the shoe. 1 ,l l

We have shown an anvil type bed 25 composed 'of an upper member 26 anda lower member 27 having inclined plane engaging surfaces 28. -A

knurled hand wheel 29 mounted on a spindle 30 axis of the spindle is parallel with the meeting 1r inclined plane surfaces of the members 26 and 27 as indicated to avoid binding of the parts. This form of anvil type bed conveniently adapts itself to cut out machines in which; the work is disposed on the bed, or on a die mountedfon the machine frame.

-die unit. .and the die supporting plate is usually a thumb bed, While the bed is slidably extended to a con- 'venient work applying position and in which the bed is then moved to operating position. Within the bed may be incorporated a guide plate 33 which engage tracks formed by upper retaining members 33a, and lower channeled portions 34 in the upper member 26. This construction assists in controlling the movement of the'member 26 on the member 2'7. The guide plate 33 carries a guide support member 35 which serves the purpose of an additional support for the Work or the die. i y

The upper surface of the member 26 is provided with sharp angular ribs as indicated at 40 so that when used to support a at undersurfaced die, small chips of cut-out .work or debris will be cut and fall into the grooves between the ribs so as not to interfere with the correct alignment of the die. y

The guide plate 33 has a pair of vertically slidable pins 37 which are retained in bushings 38. The pins are threaded at their ends as indicated at 39 for` mounting Yin threaded holes lin the While the upper member, and the lower member may be slidable on guide rails 36, the guide plate acts as an auxiliary guide. The guide plate 33 is, through its connection with 'the machine frame, fixed except for vertical movement.

As channels are formed between the members 33a and 34 which enclose the extended edgesof the guide plate 33 the movable die supporting assembly is restrained from lateral deections byguiding means intermediate said assembly of the relatively movable members 26 and 27. Thus lateral deiiection is prevented in the `upper member 26 by the guide plate 33. The plate 33 is itself restrained from lateral deflection by the permanently fixed pins 37 which, as` has been noted, only allow Vertical elevation of the bushings which are `permanently secured .in the slide.

Extending up from the sides of the lower member .2'7 are the lateral guides 41 which have `.flanged extensions 42 which engage slanting tracks 43 in the upper member 26.

Itris `a particular feature ofour invention that Ythe support 26 is -of maximum width tohave clamped thereagainst diflerent interchangeable -Ydies -regardless of their width and still allow closed uppers to be drapedthereabout or fitted uppers to be draped about its side without buckling. A

:die-consisting of a supporting plate and with cutfting instrumentalities facing upwardly may .be

mounted `on the upper surface 40 of the `upper member.y We refer to such a combination as a The connection between the member 26 nut on a shank which engages the slot 44. The auxiliary `support 35 is also medially located so vthat no matter how narrow the supporting plate of the die or what the arrangement of the pattern of the cutting instrumentalities, the die unit can be properly supported. Thus, irrespective of its width die units are interchangeable on the support.

Having thus described our invention, what we claim asnew and desire to secure by Letters Patent, is:-
